There are several scales for measuring hairloss. The most popular is the Norwood system, which measures overall pattern of hairloss and is based on the previous Hamilton system. More specific scales for density, frontal lost, middle loss, and rear loss exist and are known as the 'Savin Scale.' A separate scale exists for female pattern hairloss known as the 'Ludwig Scale.'
